' f SPINNINGOH WINDING MACHINE.

Laoiaayf Y T01 all which@ limiti/concern.' i f Be it` fknownfthat` I, HARRY AfLEoNARp, a citizen ofv the United States, residing in Hopedale, inthe/county of1Woroester and StateA of; Massachusetts, have ,invented an Improvement in Spinning yor Winding Machines, of'. which the following description,

-in lconnection with the accompanying drawi ings,is-a specificatiom-like 'characters on the drawings representinglike parts. -'r c The inventionxto be hereinafter described krelatesto spinning or winding machines for winding fyar'n on; carriers'- orf bobbins, and

\ morev particularly to the builder mechanisms of such machines. Y Y.

`In loomsjof the. automatic type wherein a feeleris employed-to feel 'for the yarn in the shuttle and initiate replenishment of filling prior tofcomplete exhaustion thereof, it is preceding replenishment. -This has been ac- Y Vcomplishedrin some .cases by placing one or morelayers of iilling on the carriers or bobbins tol constitute asuita-ble supply for the purposes stated before the regular or service windings are commenced-f lSuch .suitable supplyhas been furnished by preliminary windings'ofdii'erent traverse :from the regular orl service windings, or bythe formation of la distinctive bunch. Where the carriers` i or bobbin's have. been lslotted or recessed for the. reception ofthe feeler at the critical period, it has been proposed to place the'prel liminary windings or bunchator beyond bobbins. :An important feature'of"theinvei'i-V tion consists of two cams, one a primary Vone endof the-slot, so thatfwlien the feeler calls va change such .bunch orl windings have constituted thejreserve supply.

. The present inventiongprovides simple and effective means forproducing such preliminary windings or bunches, and while espe- 1 cially adapted for placing a reserve supply 45 of lyarn upon slotted carriers orbobbins, it

mayv alsobe employedwwith'advantage .inl

The invention is herein illustrated as applied to a spinning machinerof the ring type, wherein the niain frame l is provided with the crossfpiece or ladder 2, the top .rail

of which suppo-rts'aseries `of spindlesprovided with'whirls or pulleys 3 for rotatingaY series of yarn carriers or bobbins 4L mounted. on the spindles. A lifter rail 5 has aseries of rings 6 provided with usual travelers, and isL supported by the lifter rod 7, the lower end 8 of which rests upon a stud or roll '9 adju'stably mounted jon the .lever 10 pivoted at 11 upon a suitable bracket 12 extending from the lower lrail of the ladder 2, and provided with a weight 13 for eii'e'cting upwardl traverse or movementto the ring rail.- EXIL tending upward from the lever 10 is a seg-4 .ment arm lito which is. connected oneend of a'chainilby suitable means, such as lthe adjusting vscrewy 16, the other end of the chain being secured to the winding drumv 17:

carriedjby the builder arm 18 which is itself*V pivoted at 19, Fig. 2, to a suitablesuppo-rt. While only asingle lever and lifter'rod 7 areillustrated, it is to be understood that Y anysuitable number of these may be employed and the levers maybe connected, as

' usual, to mo-ve in `unison and cause the ring rail 5to move up and down under control ofthe builder motiomas is common and well understood in this general class Offmachmes..

vThe drum 17, Fig., 2, is mounted on the ybuilder arm 18 and is connected for rotative Vmain frame 1 is the cam shaft 26, which may i be actuated from any suitable source 'of power, V`as 'by thegear wheel 27,Fig.` 1.

VVConnected for rotative movementwith the Vcam shaft 26 are thev primary winding cam and the service winding cam. In the present instance of the inventiomthemain frame 1, Figs. 6 and bearing 28, through which the cam shaft 26 extends and secured to Jt'he end portion 29 of Y the cam shaft 26 is the -service winding cam 30. The servicewindingcam 30 may be Y secured to the shaft 26 in any appropriate manner, but as herein shown, the cam is provided with a hub portion 31 which extends over an exterior bearing portion 32 ott-he bearing-28,v and the service windingcam is Vheld to the the cam shaft 26 by a rsuitableendl securing means 33'." The hub portonBl vof the service Winding cam I,has mounted thereonthe primarywinding cam 34' which is secured tothe service winding` cam for ro-V tative movement therewith, and in unison with the vcam shaftf 26. In the present instance, the primary winding cam 34: is* splined or keyed to the hub ofthe service' Y winding Vcamk 3Q as at 85., Figs.' 6 and 7, the

construction being such that kwhile thepri-` vmary'winding cam 34: and the service-wind-,j V'ing cam 30 rotate in unison, the primary w'ard and from the service windingfcam for winding cam has sliding axial movement to- Y apurpose that will presently appear.

:Between the primary winding cam 34 and Vthe service-winding cam 30 is interposed .yielding means normally Vacting to move thev Y cams'axially and relatively in a direction of separation. -Ink the present instance the Y Vyielding means consists of-a series of springs y 3.6,' each of-which may be'properly:supportedy in sockets v37 formed' in-or as part of the 7, has connected theretov the servicewinding cam 30. I Obviously, the

number of springs 36 may be varied, but in Vthe present instance, four of such springs are indicated as tendingA normally ."to move the y primary winding'can 34; axially away from the service winding cam 30.

The form and character or the primary winding and service winding camsv may be varied'to vsuitV the particular conditions of use,butinvthe present instance the service winding Ycam 30 has four cam portions about its periphery, each of which servesvto cause f an upwardand downwardV movcmentof the ring-rail 'orfyarn guides.' Thel primary windin -cam 34 as indicated in fFigs. 2 and y 3, vis a apted to `be moved into operative relation withthe builder arm and after the prescribed number-of traverses of primary windings have been made under its control tobe automatically vmoved out of such optake complete'control. In the present 1nerative relation'with the builder arm yto per'-Y *f mit the service winding cam\ 30 to at once stance ofthe invention, the primary winding cam has a traverse-controlling portion to impart to the builder armfthe desired'- number Vof traverses to produce the preliminary windings, and the servicewinding cam and'lprimary windin' cam lare set with respect to each other in'ixed rotativeposiofthe service winding` camk the primary winding cam shall present its traverse controlling portions. This sety condition or relation of the two cams is suchzthat the primary winding cam comes-into action-at a point 3,9, for instance,'after'the ring-rail tion so that between the highest points 38 f oryarn guides havebeen raised by the serv- Y ice winding cam acting upon the builder arm betweenl the points 38, 39, as indicated in Fig. 2. That is, whenk the primary windings are started, the ir'st' movement of the ring-rail orryarn guides is downwardly or toward the base of the bobbin oryarn carrier, and thereafter'the` ri'ng-rail'is given' thel prescribed number 'of alternate traverses, dependent Vupon the'character Vof the primary windingvcam.- Whereathe invention is applied tothe winding of carriers or bobbins having slotted or recessed portions into which thefi'efelerY extends at times, the set position ofthe'camsis-determined so as to place the primary windings at oneend carrier.'-V Y constructionyas indicated vin Figs; 2 and 3,' it

will be notedfthat as soon as the preliminary Vof the slot or recessed'portion, 'preferably vtowardthe` head or base ofthe bobbin or From aninspection of the cam'V windingsh'aveibeen laid upon the carrierv or bobbin, the full service traverse com- #Mounted upon f the builder arm 18 is a roll 40 which may be adjustably supported by la stud shaft-'41* carried by thebuilder arml or a bracket 'secured thereto, whereby v e'o the primary winding and the service winding camsmay imparttraverse movement to Vthe builderzarm.

cam l34 away rfrom the service winding cam 30 and-such relation continuesduring serve ice winding. When,however, it is desired to commence lthe windinor operation -on afresh set of carriers vor ybobbins and to produce primary windings or a bunch, the primary windingcam 34 visV moved toward the'traverse cam 30 to bring its cam portion into operative relationl with the builder `arm and' its roll 40.v In the present instance vof the invention this is effected by av manually-contr'olledA lever 42, F figg-1,?- having' la handpor'- `bracket appropriatelysupported, and in the present yinstance shown asfsecured tothe frameof-the machine. The lever142 hasse-V cured thereto or formed as-integral there? with a toothed segment '46, the Ateeth 47 of which engage teethj48" of a segment 49;.secured to'a rock shaft' 50. The rock shaft 5'0 may be supported in any convenient manner, but'as indicated in the present instance Vof the invention, the bearing' l28 vsupports the rock shaft below the shaft 26. Secured'to the rock shaft 50 at'each side of the caml shaft 26 are the fingers or dogs 51 which, when the primary winding' cam 34 is moved tothe left orinto Vinoperativerelation with the builder arm, stand at one side of the face of `'said primary winding cam. The position oflthe ngersorH dogs 51 at such ltime is best indicated by dottedv line, Fig. 7. From the construction described, it will be apparent that should the 4lever arm 42 Vbe' moved contra-clockwise into thev position indicated inrFig. 1, it'will, through the connections described5f'cau'se the fingers or dogs V51 to act upon Lthe Vll'jrimary winding cam 34y and move it in oppositionl tothe springs 36 to 'the`right, or into operative relationvr with 'the builder arm 18 Aand itsfr'o'll 40.

. To -holdithe primary winding cam 34 vin operative relation with the builderv arm, a lock is" provided. lIn thepresent "instance of theinvention, the lock comprises a member 52adju'stably secured to the builder arm by suitable means such as .the'bolt 53. The* end portion of the lock member 52 is adapted to bear upon the face of thecam 34 whenv such cam is in operative position relativeto the builder arm and thereby Vlock the camA from movementv axially of 4the `camshaft/by the springs' 36;" ',Bymou'nting the lock52 upon the builderv arm, it may be conveniently low-v Y ered by foot depressionv of thebuilder `ar'm toyk moved into operativev relation, with the.

permit the" primary winding'cam n34v to be builder arm or'towardtheservice winding cam 30.h This movement of' the primary winding lcam may be eli'ected in various ways, one convenient form of lmeans for this purpose being the lever 42. When the primary winding cam has been moved into operative position it may be held there by the lock 52 which rises behind the cam l34 when *the footis removed from the builder arm'. If desired,I the buildervarm lmay be conveniently lowered Jfor engaging the. lock 7*-5 behind 'the cam byother means thanthev foot of the attendant. The primary windingcam has a series of openings or slots 54,

any oneof which, when. in alinement with the lock, may permit'the' primary winding 80 cam to move away from operative position. When bobbins lor filling Vcarriers areto be wound for use in broad looms, a greater quantity of reserve filling is required in the primary windings than where the carriers are to be used in narrower looms, and the present `invention contemplates means Jfor adapting the builder motionto either ofl these requirements. `In the present instance of the invention, the primary windingcam has foul-slots 54 whichpermit movement o'f the cam away from operative relation with the builder arm at any one of four positions Vof the primary winding cam, the periphery of the cams being such between any ltwo of said vslots 54 to efl'ectwindings oruse in looms of ordinary width. In prep'aring'the filling carriersv for `such use, the attendant depresses the builder arm at the appropriate time, then shifts the primary winding cam into operative position or close to the service winding cam, whereupon the builder arm is permitted to rise, thereby placing the lock 52 back'of the primary winding cam, substantially as indicated iny Fig.11. f As the cams revolve the desired traverse will be imparted tov the'ring-rail, until, when Van ade vancing slot 54 comes opposite the; lock, the primary winding cam'w'ill be at once moved into inoperative position by the vsprings 36, and service winding will be resumed. f

When, however, lling carriers are to be prepared foruse in Vbroad looms, and consequently a larger amount of reserve yarn VVis to be provided in the primary windings, it is 115 desirable that a greater number of traverses be madeby the primary winding cam before it is moved into inoperative position." To this end, `the present invention provides means to continue the locked position of the primary windingfr cam as one or more lof the slots54 of thercam pass the lock 52. In the 'present instance 01:" the invention in this respect, a latch is provided for holding thek primary cam in operative position, asV a slot edj at57 to Ythe bracket 45. A' Weight 15.5 connectedv to the arm 55, or a spring 58', one

- end of QWhich is secured to the. armV 55, and

theother tothe bracket 45k as indicated in Fig. 4, may serve to normallythroW thef latch tothe left, Fig. 5, into'lockingposi.- tion above the toothed segment 46,-thecon'-,

struction being such that when the lever arm 42 has :beenthrown into the .position indi- Vv cated in Fig. 1, the fingers or Ydogs 51 Will-VK move the primaryV Winding cam 34 intothe position indicated in Fig. ,6, .whereupon the latch 55 will engage'above the. toothed segment arm 46 and maintain'thedogs 51 press.- ing .upon and holding the primary cam l34in operative Y position to which it has been moved bythe-dogs. Itis evident thatso long vasthedogs thus holdV the primary foam,

theV latter cannot move to inoperative posireleaseV the primaryvvinding cam to Ymovement after oneof theslots y54 ofthe camhas y traveled pastthe lock52. To this AVend the latch 55 has a Vtripping device, Whichinthe presentinstance of the-invention, is mounted at 59 on the latch and has a shouldered portion 60 and a trip finger 61. yPins 62 attached to the service cam 30 are adapted to Y engage and move the nger 61.- These pins may be made removable, so thatWhen-laying primary windings for broad loomsa Zpin62 may be placed in alternate holes162 of the cam, thereby permitting the latch -to hold the Y dogsand perforce, the primary Winding cam inoperatmg position While one of the slots V54 passes the lock 52 andthen, .tripping theY latch, sojthat upon a half rotation of the primary Winding Cam, thel-atter may automatically moveto inoperative position. AIf* all four ofthe pins-62 are secured to the cam* '30,' fthenzxthe Y attendant may depressy the builder arm to permit the lprimaryv Winding cam'to l*move into: operating position and' hold v-the arts insuch position until-.after the ,first p m adjacent the v'trip 4has-passed the y trip finger 61. This is preferred .in some in'- stanCeS, as it does avvay With lthe attendant putting in and taking out the pins.
